More young people voted for Bernie Sanders than Trump and Clinton combined — by a lot

Despite Hillary Clinton's delegate gains on June 7, presidential candidate Bernie Sanders promised to "continue to fight for every vote and every delegate," until the Democratic convention. He also slammed GOP rival Donald Trump as "a candidate whose major theme is bigotry." (Jenny Starrs/The Washington Post)

It's hard to overemphasize how completely and utterly Sen. Bernie Sanders dominated the youth vote to this point in the 2016 presidential campaign. While Hillary Clinton dominated him among older voters, he dominated her right back among younger voters -- even winning more than 80 percent of their votes in some states against no less than the eventual Democratic nominee.

But this fact might say it better than any: In the 2016 campaign, Sanders won more votes among those under age 30 than the two presumptive major-party presidential nominees combined. And it wasn't close.

Clinton and Donald Trump combined? Less than 1.6 million. Sanders, in fact, won about 29 percent more votes among those under the age of 30.

And that number actually rose as the campaign went on. Back in mid-March, we looked at the same numbers and found Sanders had about 25 percent more votes than Trump and Clinton combined. And despite Clinton effectively locking up her party's nomination around that point and Trump's opponents starting to drop out, Sanders actually extended his advantage late in the campaign.

It's also worth noting in all of this that Sanders's domination among young voters has caused this surprising stat: To this point in the campaign, for the states where we have exit polls of young voters, more young people have voted for the presumptive GOP nominee for president than the Democratic one. Yes, that's right: Trump has more youth votes than Clinton.

That, of course, is not because Trump did great among young people. It's because Sanders was a phenomenon -- and perhaps also because Clinton has work to do with young people. It won't be the case in the general election, either. Even if young voters don't turn out as strongly for Clinton as they would have for Sanders, a Republican hasn't won the youth vote since 1988, and the margins have become massive.
